Mapping the urban landscape at multiple ecological scales
Urbanization is increasing worldwide, driving the expansion of urban areas and resulting in habitat loss, fragmentation, and changes in environmental conditions. Despite these pressures, urban landscapes can still support biodiversity, provide essential ecosystem services and contribute to conservation. Several metrics exist to characterize landscapes, but the spatial scale at which they are relevant depends on species ecology or on the ecological process of interest. Rome, one of Europe’s oldest cities, has experienced continuous urbanization over centuries while maintaining a remarkable level of greenery. This study explores the landscape structure in Rome using a multi-scale approach. We analyze key landscape metrics—Green Area Proportion, Edge Density, Shannon Diversity Index, and Edge Distance—across four spatial scales (10 m, 50 m, 250 m, and 1250 m), which are relevant for the ecology of a wide variety of plant and animal organisms that occur in the city. We show that these landscape metrics can be summarized by two major axes representing urbanization and fragmentation, respectively, and allow for grouping Rome green areas into three types (homogeneous green areas, highly impervious areas, and impervious surfaces interspersed with small green spaces). The high-resolution raster data generated in this study can lay the foundation to test how these axes at different scales and theresulting landscape types can shape urban species assemblages
期刊介绍:
Urban Forestry and Urban Greening is a refereed, international journal aimed at presenting high-quality research with urban and peri-urban woody and non-woody vegetation and its use, planning, design, establishment and management as its main topics. Urban Forestry and Urban Greening concentrates on all tree-dominated (as joint together in the urban forest) as well as other green resources in and around urban areas, such as woodlands, public and private urban parks and gardens, urban nature areas, street tree and square plantations, botanical gardens and cemeteries.
The journal welcomes basic and applied research papers, as well as review papers and short communications. Contributions should focus on one or more of the following aspects:
-Form and functions of urban forests and other vegetation, including aspects of urban ecology.
-Policy-making, planning and design related to urban forests and other vegetation.
-Selection and establishment of tree resources and other vegetation for urban environments.
-Management of urban forests and other vegetation.
Original contributions of a high academic standard are invited from a wide range of disciplines and fields, including forestry, biology, horticulture, arboriculture, landscape ecology, pathology, soil science, hydrology, landscape architecture, landscape planning, urban planning and design, economics, sociology, environmental psychology, public health, and education.
